KJE writes: "The CBC is reporting that an Ontario teachers' union is calling for an end to new Wi-Fi setups in the province's 1,400-plus Catholic schools. The Ontario English Catholic Teacher's Association (OECTA) says computers in all new schools should be hardwired instead of setting up wireless networks. The OECTA, in its paper (PDF), said the "safety of this technology has not thoroughly been researched and therefore the precautionary principle and prudent avoidance of exposure should be practised.""
